SPECIFICATION forming part f Letters Patent No. 602,195, @lated April12, 189s.

Application fusil July 9, 1397. serial Nb. classi. (No modela To @ZZwhom, t may concern.:` Be it known that I, CHARLES YPEAU, a citizen ofthe United States, and a. resident of the city of Cincinnati, in the'county of IIamilton and State of Ohio, have invented certain new anduseful Improvements in Water- Closet Tanks and Their Attach ments,ofwhich the following is a specification.

The primary feature of lmy invention relates to a construction wherebythe watercloset tank can be readily attached to the wall and detachedtherefrom.

The several features of my invention and the various advantagesresulting from their use, conjointly or otherwise,.will beapparent fromthe followingspecification.l

l In the accompanying drawings, making a part of this specification,Figure l represents a rear elevation of a water-closet 'tank' andconnecting-piece, illustrating my invention. Fig. 2 is a verticalcross-section taken in the plane of the dotted line 2 2 .of;`Fig. V1.`Fig;

3 is a rear elevation'similar to that shown in. Fig. l and showing vaslight' modification of f some details'ofconstruction. Fig. 4 representsa transverse cross-section. taken in the plane of the dotted line 4 4'of Fig. 3.Y

A indicates a water-closet tank of `any preferred form atfrorlt andsides. In the present linstance the tankis rectangular, and viewed fromabove is somewhat longer than wide.

Heretofore it has been difcult for the p'urchaser of the water-closettank to put up the tank. Unless personally a skilled workman with timeon his hands he has been obliged to employ such a one, and he or theworklnan obtain materials with which to properly locate the Water-closettank in the closet. One of the objects of my yinvention is to lightensuch labor or Wholly dispense with it. Y

The severalfeatures of my invention and the various advantages resultingfrom their use, conjointly or otherwise, will be apparent from thefollowing description and claims.

F indicates the front of the tank. I recess the back of the tank and Idenominate this recess as R. For example, I set the back B forward,allowing the side rear edge of the sides C C to project rearward beyondit. The upper end of the tank is usually open. I

vsides C.

vallow the rear edge ofthe bottom Dito project beyond the plane of theback B at certain points, as hereinafter described.

I provide a broad sheet of suitable material E, (wood is usuallypreferable,) and I shape this so. as to be of the length and height ofthe back B.

I attach to the backB of the tank at its top edge one or moreangle-irons G, (two are preferred,) Whose hooked ends G2 extendvertically down and do not extend rearwardly beyond the plane of therear edges of the The thickness of `the auxiliary back piece ispreferably about the depth of the recess, and in such event the upperrear part of this auxiliary back is cut away, forminga recess E2. It isin this recess the hooks'lie when the tank is attached to the auxiliaryback.

The lower edge of the auxiliary back E, I

provide with a lateral 'flangeH, extending` each way from thecenternearlyto thefends. The lower corners of the'auxiliaryback are cut away,forming the recesses E3, and these recesses are high enough to" allowthe hooks G of the tank to clear the top of the auxiliary back and allowthe latter to run vertically into their embrace; while the back B of thetank is moved toward the" auxiliary back E.

The lower rear edge of the bottom D is cut away, so as to admit thecentral portion E4 of the auxiliary back E. The flange I-I overlapsbelow the portions D of the bottom, thus concealing the joints from Viewand making a presentable and pleasing appearance.

The manner of applying my invention is readily understood, viz:` Theauxiliary back is securely fastened to the'wallor like support. Thewater-closet tank is then lifted a little higher than the level of theauxiliary back and moved toward it. the tank are hooked over the back E,their free ends lying in the recess E2 of said back E. The bottom ofsaid tank is nowadvanced until the back of the tank at the bottom comesagainst the front of the back E. The tank is now allowed to settle untilit rests on llange I-I of the back E. It is this flange II of back Ethat supports the direct weight of the tank and its contents. The hooksG pre- The hooks G of IOO vent the top part of the tank from leaving theback E. Thus the tank A is securely held in place and the joints of itsconnection with the auxiliary back at bottom are concealed from view. Asthe tank is always (except in rare instances) located overhead, allconnections with the auxiliary back are concealed from view. The tankcan at any time be removed from the auxiliary back by reversing theoperations above specified.

It will be understood that the necessary conduit connections, forsupplying water to the tank, and delivering it to the closet, will besupplied as usual.

In the modifications illustrated in Figs. 3 anda the angle rims orflanges H2 are substituted for the single long flange H, and upon thesame principle, as the bottom is cut away as shown in Figs. l and 2, soin this modification the bottom D is cut away only sufficiently to allowthe vertical portionH3 to enter the rear bottom edge D of the tank, and,as in the case of flange H, so in the flanges H2, the bottoms H4 extendlaterally beyond the width of the vertical parts Hi of the angle-ironsand effectually conceal the openings ot juncture between the edge D andthe said vertical parts H3. The tank is placed in position and removedtherefrom in like manner as in the construction shown in Figs. 1 and 2,and the tank rests on the bottoms or flanges H4, as in the former caseit rested on flange H.

What I claim as new and of my invention, and desire to secure by LettersPatent, is-

1. The combination of a water-closet tank having a recessed back withrearwardly-projecting side edges, and rearwardly-projecting bottom edge,and having the upper back hooks, and the supplemental plate, recessed atrear to receive the limbs of said hooks, and having the lowerforwardly-projecting flange adapted to extend under the tank, and therear edge of the tank-bottom cut away to receive that part ofthe backwhich supports the said bottom flange, substantially as and f'or thepurposes specified.

2. rlhe combination of a water-closet tank having a recessed backwithrearwardly-projecting side edges and a rearwardly-projecting bottomedge, and having the upper back hooks, and the supplemental plate,recessed at rear to receive the limbs of said hooks, and having thelower forwardly-projecting flange adapted to extend under the tank, andthe bottom edge of the tank cut away to receive that part of thesupplemental back which receives the said flange, that part of the backbeing contracted in width and less than the length of the flange, theremaining rear edges of the bottom of the tank and their joint with thesupplemental back being covered by the extended flange of the back,substantially as and for the purp'oses'specified.

3. The combination of the supplemental back contracted near the bottomand terminating in a flange extending forward and beyond the adjacentedges of the back, and the water tank having sides extending rearwardlybeyond the back, and parts of the bottom also extended rearwardly andover the flange and assisting to conceal joints, substantially as andfor the purposes specified.

t. In a water-tank elevated above the floor, the combination of thesupplemental back, having bottom 'forward projection, and the tankhaving the upper hook-formed device for engaging the upper edge portionof the supplemental back, the tank being free to swing and rest againstthe lower part of the su pple mental back, and being supported by theextended bottom flange of the latter, substantially as andfor thepurposes specified.

5. In a water-tank elevated above the floor, the combination of thesupplemental back having bottom forward projection, and contracted justbefore it reachesthe projection, and leaving the projection extendinglaterally beyond the neck, and the tank having the upper hook-formeddevice for engaging the upper edge portion of the supplemental back, thelatter recessed where the engagement with the hook-formed device takesplace, the tank being free to swing and rest at its lower portionagainst the lower part of the supplemental back and being supported bythe extended bottom flange of the latter, 'substantially as and for thepurposes specified.
